    MANUAL PROCESSING:MULTI-SPECIES STUDIES

    45 cameras x 150days x c.30sp

    Camera arrays Create very large data sets

    Multiple species

    Multiple data manipulations required

    Lack of central data management system

    High potential for errors in manual data handling

    Files tend to proliferate during manual analysis

    Lack of standardisation in manual analysis

    Very slow, loss of data, incomplete analyses/reports

    No equivalent package available (when projectstarted..)

    What does it do? Phase 1 Targetedat processingdata from camera arrays

    Manages multiplesurveys within a single database

    Calculates and reports survey effort

    Permits data filtering, image checking, processing andcorrection

    Provides standardised data model

    Outputs:

    Species lists (sortable by Class, trophic level etc.)

    Species richness

    Trapping rates (user definedevents)

    Occupancy analysis

    Plots distributionof records

    Activity patterns

    Temporal trends
